Cinnamon Bug

A bright red-and-black scentless plant bug that mimics fire bugs and other aposematic insects. Despite its warning coloration, it is harmless and feeds on the seeds of various weedy plants.

💡

Did You Know?

It is often mistaken for the unrelated fire bug due to its similar red-and-black pattern, a likely case of Mullerian mimicry.

Oleander Aphid

A bright yellow aphid with black cornicles and legs that feeds on oleander, milkweed, and other plants containing toxic cardiac glycosides. It sequesters these toxins for its own defense.

💡

Did You Know?

Its bright yellow color serves as aposematic warning coloration because it sequesters cardiac glycosides from its host plants, making it toxic to most predators.
